Notably, since 2007, there has been a negative correlation of -76 % between the 6 - month drawdown in the S&P 500 and the 40 - week growth rate of the monetary base (with a 10 - week lag - the deeper the market loss, the greater the monetary response), and a positive correlation of 54 % between the 40 - week growth rate of the monetary base and the
subsequent recovery of the market, resulting in a negative correlation of -34 % between the 6 - month drawdown in the S&P 500 and the advance in the S&P 500 itself
over the following 40 weeks.
